[Drifting Contact] = gives you 10 more seconds to your combo duration which means you will have a total of 15 seconds before you combo multiplier resets
Try to bring your combo multiplier to 12 for fun (you will see your weapon does only orange crits)

Careful: This aura is way better than the others for moving forward and attacking at the same time.

[Blood Rush] can be left unmaxed for a while (save up your endo for mods that you use in your warframes, theres are many mods that are very expensive to max)
